HEMP-BREAKING MACHINE.

Specification of Letters Patent.

Patented Feb. 26, 1918.

Application filed July 17, 1916. Serial No. 109,642.

To all whom it may concern:

Be it known that I, SAMUEL B. CARR, a citizen of the United States,residing at Harrodsburg, in the county of Mercer and State of Kentucky,have invented anew and .useful Hemp-Breaking Machine, called the CarrAutomatic Hempbrake, of which the following is a specification.

The present invention appertains to hemp breaking machines, and aims toprovide a novel mechanism for operating a machine of that character byan engine or prime mover in an effective manner.

It is also the object of the invention to provide a mechanism of thenature indicated which is comparatively simple and inexpensive inconstruction, as well as being eflicient and practical.

The invention is illustrated in the accompanying drawing, wherein Figure1 is a plan view of the improved machine.

Fig. 2 is a side elevation thereof.

In carrying out the invention, there is provided a suitable frame 21,provided at one end with a shelf or auxiliary frame 22 connected theretoby braces 23 and adapted to support an engine or other prime mover foroperating the machine. The frame is provided at its other end with across piece 9 to which the lower set of swords or blades at is attached,their free ends having attached thereto the bottom sword bar 1. Theupper set of swords or blades 1 of the breaking device is fulcrumed orpivotally connected with the frame above the cross piece 9, and haveattached to their free ends, the upper sword bar 2, springs or otherbufiers 3 being provided between the bars 1 and 2 for reducing the shockwhen the bar 2 is swung downwardly. Rigidly united with the upper set ofswords 4; and disposed above the same, is a longitudinal bar 5, and anoperating lever 6 is attached to a transverse rock shaft 10 mountedwithin the frame sub stantially in the same horizontal plane as thefulcrum of the upper set of swords 4: but spaced therefrom, whereby thelever 6 eX- tends over the fulcrum of said swords. The

free end of the lever 6 has the downwardly extending slotted member 7slidably engaging the bar 5. A transverse crank shaft 15 is journaled tothe upper portion of the frame above the intermediate portion of thelever 6, and its crank is connected by a link or connecting rod 8 withthe intermediate portion of said lever 6. A fly wheel 11 is preferablysecured upon one end of the crank shaft 15 to provide for the uniformoperation, and a pulleywheel 12 is connected to the other end of thecrank shaft and is connected by a belt 18 with a pulley wheel 13 mountedupon a counter shaft 16 carried by the frame above the rock shaft 10.The pulley wheel 13 is in turn connected by a belt 19 with the pulleywheel 14: upon a drive shaft 17 carried by the rear portion of the framenear the shelf 22, and said pulley wheel 1 1 can be connected by a belt20 with an engine or other prime mover (not shown) supported upon saidshelf, whereby to transmit motion to the crank shaft 15. By theprovision of the lever 6 having its free end slidably connected to thebar 5, and the link 8 connecting said lever 6 with the crank of thecrank shaft, the rotation of the crank shaft will effectively oscillatethe upper set of swords.

Having thus described the invention, what is claimed as new is 1. A hempbreaking machine embodying a frame, a set of swords fulcrumed thereto, abar connected rigidly with said swords, a lever fulcrumed to the framebeyond the fulcrum of the swords and having its free end slidablyengaging said bar, a crank shaft carried by the frame, and a linkconnecting the crank of said shaft and said lever. i

2. A. hemp breaking machine embodying a frame, a set of swords fulcrumedto one end of the frame, a bar connected rigidly with said swords anddisposed longitudinally thereabove, a lever fulcrumed to the framesubstantially in the same plane with the fulcrum of the swords andspaced therefrom, the free end of the'lever having a slotted portionslidably engaging said bar, a crank shaft carried bythe frame above saidlever, and a link connecting the crank of said shaft and theintermediate portion of said lever.
